Which outcome follows when excessive groundwater saturates Roman concrete?

💡 Explanation

Water saturation causes increased hydrostatic pore pressure and reduction in the interlocking capability of the aggregate through hydraulic action, leading to decreased load-bearing capacity because of reduced concrete cohesion; therefore structural integrity is reduced, rather than increased strength.
